Operation management apparatus, operation management method, and operation management program

Abstract

An operation management apparatus includes an air conditioning thermal load prediction unit configured to calculate an air conditioning thermal load predicted value indicating a predicted amount of heat required to adjust temperature to a pre-set temperature on a day-of-prediction, a power generation output prediction processing unit configured to calculate power generation output prediction data indicating a generated power obtained by a generator within the day-of-prediction, and an operation planning unit configured to prepare an air conditioning heat source operation plan, and determines a purchased power and the generated power using the power generation output prediction data to thereby prepare a power facility operation plan indicating a schedule of a power output from the purchased power source and the generator, so that the purchased power per predetermined time supplied from a purchased power source of a commercial power system becomes a target value.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority on Japanese Patent Application No. 2010-224127, filed Oct. 1, 2010, the contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to an operation management apparatus, an operation management method, and an operation management program, which may manages an operation plan with respect to a power supply device for supplying a power demand to a load device and the load device.[0004]2.

It is necessary for the power company...

AI Technical Summary

Benefits of technology

The invention provides an operation management system for air conditioning heat source facilities and other large power load devices. The system includes an air conditioning thermal load predictor, a power generation output predictor, and an operation planning unit. The system can predict the amount of heat needed to adjust temperature and the amount of power needed to generate that heat. It can also determine the amount of power needed for the load device and adjust the operation plan accordingly to ensure that the desired power output is achieved. The system can also adjust the power demand to match the predicted power output, reducing the amount of power needed and improving efficiency. Overall, the invention allows for effective demand control and optimization of power usage for large power load devices.

Problems solved by technology

However, when adjusting the load power and the power output separately from each other, the fluctuation of power consumption of an air conditioning heat source apparatus, and the like may be heavier in comparison with operation facility device such as a lighting device, a computer, and the like, and the power consumption may be locally increased in accordance with the weather or a use environment of the room.

Due to this, when the power demand is locally increased although the load device is operated according to the operation plan, an average value of the purchased power during the demand time unit may exceed the contract demand.

Thus, there is a problem in that the demand control cannot be carried out so as to follow fluctuation of a power load of the load device having a large power load such as an air conditioning heat source device, and the like.
